Vintage Sterling Silver Heart Pendant With Unknown Material Beads

2 vintage necklaces as shown in photos: the shorter on measures 16 inches and is stamped sterling silver or 925- the second necklace or ball strand is 22 inches long and I’m unsure if it’s silver plates or what? It has no marks that I can see. The balls are strung on a chain. They look nice together so I’m selling them as a set: message any questions: Take a look at my other listings as well😊.
